The concept of “LD Set” is introduced to Access Control. The concept of LD Set enables to assign
logical disks collectively to ports of multiple disk arrays and WWNs. When one single business
server has multiple access paths and if its I/O paths are duplicated or it is clustered, define multiple
access paths together by using an LD Set.
For ports and WWNs defined as paths of an identical LD Set, Access Control can be collectively set.
That is, when you add or remove an LD Set after setting up Access Control, you can collectively handle
ports and WWNs with an LD Set specified.
When a disk array with the program product AccessControl(WWN) applied is in use, only WWNs can
be defined as paths of LD Sets.
